I am art historian from Zagreb, and since you do not have information on Radoslav Putra, I am sending his short biography. Perhaps you might find useful, regardless of some serious language editing that it certainly requires. Best regards. Ljiljana Kolesnik, Institute of Art history, Zagreb Radoslav Putar (1921-1994), art critic and curator who graduated art history from the University of Zagreb in 1949, was a member of the first post-war generation of Croatian art historians, responsible for reconstruction of modernist art practices after the Yugoslav break with the USSR in the early 1950s. A director of the Zagreb Gallery of Contemporary Art from 1972 to 1979, well-informed and unwavering supporter of experimental art practices, a prominent participant of the international neo-constructivist international art movement New Tendencies, Putar was among the first Croatian art critics and curators who strongly supported the “computer aided visual research”. Among articles and public lectures outlining the history of digital art in Southeast Europe / former Yugoslavia / particularly important is his review of London 1968 exhibition Cybernetic Serendipity and its comparison with the exhibition Computers and Visual Research, which was took place in Zagreb, in August 1968, within the framework of the New Tendencies 4th exhibition.
